</p>
<ul>
<li>:<a href="Server.html#M000420">app</a>

<pre>
  a rack application to run (overrides :config)
</pre>
</li>
<li>:config

<pre>
  a rackup configuration file path to load (.ru)
</pre>
</li>
<li>:environment

<pre>
  this selects the middleware that will be wrapped around
  your application. Default options available are:
    - development: CommonLogger, ShowExceptions, and Lint
    - deployment: CommonLogger
    - none: no extra middleware
  note: when the server is a cgi server, CommonLogger is not included.
</pre>
</li>
<li>:<a href="Server.html#M000426">server</a>

<pre>
  choose a specific Rack::Handler, e.g. cgi, fcgi, webrick
</pre>
</li>
<li>:daemonize

<pre>
  if true, the server will daemonize itself (fork, detach, etc)
</pre>
</li>
<li>:pid

<pre>
  path to write a pid file after daemonize
</pre>
</li>
<li>:Host

<pre>
  the host address to bind to (used by supporting Rack::Handler)
</pre>
</li>
<li>:Port

<pre>
  the port to bind to (used by supporting Rack::Handler)
</pre>
</li>
<li>:AccessLog

<pre>
  webrick access log options (or supporting Rack::Handler)
</pre>
</li>
<li>:debug

<pre>
  turn on debug output ($DEBUG = true)
</pre>
</li>
<li>:warn

<pre>
  turn on warnings ($-w = true)
</pre>
</li>
<li>:include

<pre>
  add given paths to $LOAD_PATH
</pre>
</li>
<li>:require

<pre>
  require the given libraries

Start a <a href="Server.html#M000417">new</a> rack <a
href="Server.html#M000426">server</a> (like running rackup). This will
parse ARGV and provide standard ARGV rackup <a
href="Server.html#M000418">options</a>, defaulting to load
&#8216;config.ru&#8217;.
</p>
<p>
Providing an <a href="Server.html#M000418">options</a> hash will prevent
ARGV parsing and will not include any default <a
href="Server.html#M000418">options</a>.
</p>
<p>
This method can be used to very easily launch a CGI application, for
example:
</p>
<pre>
 Rack::Server.start(
   :app =&gt; lambda do |e|
     [200, {'Content-Type' =&gt; 'text/html'}, ['hello world']]
   end,
   :server =&gt; 'cgi'
 )
</pre>
<p>
Further <a href="Server.html#M000418">options</a> available here are
documented on Rack::Server#initialize
